10kW 3-Phase Grid Tie Inverter Reference Design for Solar String Inverter

This verified reference design provides an overview on how to implement a three-level three-phase SiC based DC:AC grid-tie inverter stage. Higher switching frequency of 50KHz reduces the size of magnetics for the filter design and enables higher power density. The use of SiC MOSFETs...
